CleanSweep AC EMI Filters provide effective noise reduction where it matters - in your environment. Many generic EMI suppression filters work well only in EMC test labs but do little or even can boost EMI in real-life installations. CleanSweep® power line filters block EMI on real life power lines (both common mode and differential mode) and, uniquely, in ground, from reaching sensitive equipment. They also reduce EMI "backflow" from a "noisy" source that otherwise would end up on your AC power network. In addition to be highly effective in reducing EMI, CleanSweep® AC filters also offer advanced transient surge protection unachievable by regular MOV-based surge protectors - see some of the performance data further on this page. CleanSweep filters are plug-and-play and can be installed in minutes without the need for an electrician.
